cannot npm install react-devtools

[AdrienLemaire]

Running:

$ sudo npm install -g react-devtools

Hangs when trying to install electron. Can be reproduced with $ npm install electron.

[AdrienLemaire]

installing electron with my package manager, then reinstalling react-devtools seems to work

[AdrienLemaire]

hmm actually, even if npm install didn't raise an error, react-devtools is still unusable:

$ react-devtools                                          [99f5547; 14:23:33]
/usr/lib/node_modules/react-devtools/node_modules/electron/index.js:9
  throw new Error('Electron failed to install correctly, please delete node_modules/electron and try installing again')
  ^

Of course, I tried to remove the node_modules/electron dir several times and reinstalling without success (still hangs)

Why are you running this command with sudo? Generally using sudo with npm is extremely error prone and leads to all sorts of issues with corrupted permissions.

[AdrienLemaire]

I used sudo because I cannot install globally as my user, something to do with the nobody user.

You should change global Node modules directory to something writable by all users. Not saying this will fix the problem but it's a better way. Npm just doesn't work well with sudo.

[bvaughn]

Did changing permissions on the /usr/lib/node_modules/ directory resolve this issue for you @Fandekasp?

I just checked and was able to npm i -g react-devtools without any problem.

[AdrienLemaire]

my react native project got cancelled, and I'm already using the chrome extension for react-devtools, so I don't need to install this locally anymore. Closing.

[AlexanderKosianchuk]

chown USER:root /usr/lib/node_modules/ resolves "EACCES: permission denied, access /usr/lib/node_module"

[lpetkovic]

Been having the same issue (wasn't using sudo for npm i), resolved it by globally installing electron and then react-devtools.

[ghost]

After fixing the permission issue with npm global install (see https://docs.npmjs.com/getting-started/fixing-npm-permissions) (I did Option 2), i do the following:

$ npm uninstall -g react-devtools
$ npm uninstall -g electron
$ npm install -g --verbose react-devtools

Then the terminal will show the downloading process:

For me it was done within 5 minutes, and then $ react-devtools works.

[brancooo1]

This does the trick for me.

sudo npm install -g react-devtools --unsafe-perm=true

[enriquesime]

@ghost Thanks that solve the issue !!!

[shafiqueqadri]

@brancooo1 Thanks your solution works for me.

[vink1987]

@brancooo1 thanks ... it works 👍

[peterfei]

@ghost thanks a lot!

[mckmarc]

@brancooo1 yeah

[alitsvin]

I've changed rights on global node_modules directory and then installed devtools
cd /usr/local/lib
sudo chown -R user:user node_modules
npm i -g react-devtools
And it installed normally

[aino-gautam]

after trying all other options - this one worked as pointed out by @brancooo1

sudo npm install -g react-devtools --unsafe-perm=true

[min9nim]

adding --unsafe-perm=true option is work for me

thanks for @brancooo1

[bbmattieu9]

What does the flag --unsafe-perm=true mean???? I used it and it worked but i do know understand what i just did. Please point me to a resource to learn this.to know.thanks

[behnammodi]

@brancooo1 thank's

[Ethanng329]

This does the trick for me.

[PrimeTime416]

--unsafe-perm=true works for me, thanks Peoples.

[gonpeche]

Faced same issue, tried several answers found on the web and the solution provided by @brancooo1 worked like a charm, thanks bro.

sudo npm install -g react-devtools --unsafe-perm=true

[nawartamawi]

you need to change the node_modules permission to all users
1- cd /usr/local/lib/
2- sudo chmod 777 node_modules
3- npm install -g react-devtools

that should fix it.

it's better to look at this link it's work
